The city got its snowbuster crews revved up last night as another winter storm blew into the Big Apple – one that forecasters say will have dumped significant amounts of the white stuff on our streets by this afternoon.

Thousands of sanitation and transportation workers armed with more than 2,000 pieces of heavy equipment – plows, salt spreaders and snow melters – started clearing the thoroughfares.

“They’ll all be out working very hard,” Mayor Bloomberg said yesterday afternoon.

“It looks like we’ll have a good 5 to 10 inches so the commute is going to be really problematic. Use mass transit and drive slowly.”

The National Weather Service said the snow could mix with sleet at times, making the streets and sidewalks extremely slippery.

While today’s temperatures will hover around the freezing mark, they’ll plummet to about 20 degrees tonight. With westerly winds of up to 20 mph, it’ll feel 10 to 15 degrees colder.

At least the latest snowstorm shouldn’t tax the city budget. “So far this season, we have used a quarter of a million tons of rock salt, and we still have 120,000 available,” Bloomberg said. “Fortunately a lot of that salt is still on the streets.”

Many of the city’s hotels were full last night with business executives who normally commute from the suburbs and feared being stranded.

The Millennium Hilton Hotel on Church Street, which usually rents about 320 rooms this time of year, had the remainder of its 565 rooms booked by Wall Street firms.

All ferries operated by New York Waterway were running, but scattered delays were expected.

“There are 21 routes and nine to 10 different terminals and the ice doesn’t stay in one place,” said ferry spokesman Pat Smith.

If you haven’t had enough snow by now, you only have to wait until Friday, when there’s a 60 percent chance of further snow predicted, with more scattered flurries on Saturday.

The next temperature break we’ll get is on Monday, when the forecast calls for the mercury to rise into the mid-30s.
